.IMPRQVEMENI INGATES Specification forming part of Letters Patent No.130,306, dated August 6, 1872.

Specification describing a certain Improvement in Farm-Gates, inventedby JAMES H. MORGAN, of Warsaw, in the county of Kosciusko and State ofIndiana.

This invention relates to that class of farmgates which are opened andclosed by sliding them endwise on anti-friction rollers; and myimprovement consists in a combination of mechanism, by means of which aperson on horseback, in a wagon, or afoot, may raise or lower one end ofthe gate and thus cause it to gravitate shut or open, as the case maybe, the details being explained generally in the following descriptionand specitcall y pointed out in the claim.

Figure l is a front elevation of the improved gate shut, showing part ofthe extension-rail in section. Fig. 2 is a similar view of the gate slidopen. Fig. 3 is a transverse section.v

The same letters of reference are used in all the figures in thedesignation of identical parts.

The upper rail of the gate A is prolongated beyond the length of thegate proper to form the extension A', which should be somewhat longerthan the entire extent of endwise movement of the gate. B and O are theY gate-posts, and D is an additional post located the proper distancefrom the post B, and carrying near its upperend two anti-frictionrollers, d and d', between which the extensionrail A' runs. The rollersare constructed with tongues on their peripheries to enter correspondinggrooves a al in the rail, as shown in Fig. 1. Aside from the support thegate derives from the rollers d and d', it is suspended upon avertically-movable anti-friction roller, E, by its top rail, which has agroove, a2,'in its lower edge fitting a tongue on the roller, as bestseen in Fig. 2, this roller being arranged on the middle post B. rlhisarrange,

ment of grooves inthe top rail of the gate, and in its extension A' andcorresponding tongues on the anti-friction rollers sustaining the gate,

provides everything necessary to steady the gate and cause it to move instraight lines. The post B is composed of two sticks of timber with anintervening space, in which the gate is arranged, and a slot is cut inthe upper end of each stick for the reception of the frameY F, which issuspended from the ends of the levers G and G'. The roller E isjournaled in the lower ends of the bifurcated frame, and the relativearrangement of the parts is such that when the downward movement of theframe is arrested by the ends of the slots in which it moves the gatewill have a downward inclination toward the post (l, and its own gravitywill cause it to slide endwise toward that post to close the gateway.If, on the other hand, the frame F be raised to its highest position bythe levers G or G', the gate will be raised until it obtains a downwardinclination toward the post D, when it will automatically slide towardthat post and open the gateway. The levers G and G' turn on studs g andg' on a cross-bar, B', of the post B, are made ot' any required length,and should be made of just suicient weight to counterbalance the gate,so that it will need only a slight exertion to raise or lower the gateand cause it to open or shut.

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the sliding gate A A', stationary anti-frictionrollers el d', movable anti-friction roller E and frame F, andoperating-levers G and G', all arranged in relation to one anothersubstantially in the manner and for the purpose set forth.

In testimony whereof I have signed my name to this speccation in thepresence of two subscribing witnesses.

JAMES H. MORGAN.
